To all whom it may concev'nf i Be it known that we, WILLIAM E. RAMAGE and HENRY D. Snaw, citizens of the United States, residing athdams, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in Paper-Making Machinery, of which the following is a specification. i

yOur invention relates to improvements in paper making machinery, and particularly to an attachment for that type known as the Fourdrinier machine,

, which is well-known in the art of paper making.

series of grooves is cut in the paper to render the same more flexible in certain portions, the paper then passing on through the attachment to the sizing boxes, then calendered and finished in the proper manner.

A further object of the invention is to produce a paper which by means of the aforesaid grooves possesses great flexibility along a certain portion thereof which portion may be used as the binding edge or hinge'portions, so that the grooved or cut-away portions of the 4 paper will be quite flexible butat t-li'e' same time will possess practically the same strength and durability as the heavier portions of the sheet.

Another object of our invention is to provide simple and efficient mechanism for forming the grooves in the web of paper, and to render the said mechanism adjustable for use with paper of different widths and thickness, to cut grooves of any required depth, and to form any number of grooves or series of grooves, and to space the' grooves in the desired relation.

', To attain the desired object's, our invention comprises an adjustable platen or support over which the web of paper is adapted to pass, and a cutter wheel or series of cutter wheels arranged directly above the platen, the paper passing between theplaten and the I cutter Wheels, and the various parts being adjiistable to suit differentconditi'ons:

Our invention further comprises certain other novel features ofconstrilction, combination and arrangement oi parts substantially as herein set forth, attention being invited to the accompanying drawings, in whichf Figure 1, is a broken side elevation of the end of a Founlrlnler machine-known as the dry. end of the machine, I with my ilnpmvements applied thereto.

Fig. 2, is a similar view of a portion of my invention,

being the cilttcl' wheels and support therefor. Fig. 3, is a plan view of the supporting plate or bar for the cuttor-wheel bracket. Fig. 4, is a sectional view with m. shown in elevation to iliustmttho nmngsment,

of the cutter wheels and paper support or platen. Fig. 5, is a plan view of a portion of the base plate for the platen support. Fig. 6, is a side elevation, partly in section, of'the parts shown in Fig. 4.

We have designed our improvements so that they may readily be applied to the well-known Fourdrinier type of paper-making machinery and to such end We have shown a portion of such a machine in the accompanying drawings,in which:

The numeral 1, designates the drier frame, and 2, the last drier roll mounted therein. Rolls 3, are journaledin the frame, over which the web of paper, 4, passes, and slitters or rotary knives 5, are arranged near the end of the frame for cutting the webof paper into strips, all of the said parts being in common use.

Secured in the upper portion of the frame at a point in rear of the last drying roll, is a transverse plate or bar 6, provided with a series of longitudinal, parallel slots 7, therein, the slots being arranged in three courses, as clearlyshown in Fig. 5, and this plate forms the base upon which the paper-support is arranged. A rectangular boxing or casing 8, having a flanged base 9, is mounted upon the base plate 6, and is adjustably secured thereon by means oi the headed bolts 10, the bolts passing up through the outer series of slots in the base plate, through openings 11 provided in the flanged base, and wing nuts or clamping nuts 12, are secured upon the upper ends of. the bolts. A supporting block through the center slot therein. A thumb nut 16, en-

gaged-in the side of the boxingserves to lock the platen in its adjusted position.

Supported-above the web of paper upon the stand ards 17, is a transverse supporting bar or plate 18, which 'is' formed with adouble row of parallel longitudinal slots 19, therein. A bracket 20, is secured to the under face of the supporting bar by means of the bolts 21, which pass through theslots in said bar, so that the bracket may be'adjusted longitudinally upon the bar.

,Downwardly-inclined 311115.22, depend from said bracket and are formed at their. lower ends with the journal bearings 23, which support the shaft 24. A driving pulley-25, is fixed upon said shaft, preferably between the journal brackets, and also secured upon said shaft 'by, means of a lock nut 26, (see Fig. 2) is a series of cutter wheels 27, which are spaced by means.

oi the spacing collars 28. These cutter Wheels are I preferably of emery or hard steel, and are arranged directly above the platen so that the paper as it passes over the platen is contacted by the cutters which cutnation of parallel grooves in the web. By rotating the cutters in the direction opposite to the travel of the web of paper and at a high rate of speed, the unfinished surface of the paper is removed to the depth desired. As shown in Figs. 4 and (3, the cutters may be arranged 5 upon a b529, and spaced thereon by collars 30, the hub being secured upon the shaft by the set screw 31.

The web of paper'after it passes over the last drying roll, passes up over the guidingproll 3, and thence, preferably in a straight line, to the rotary knives and lastl0 guiding roll.

ranged between the last drying roll and rotary knives The platen and cutter wheels are 'arpreferably as shown in Fig. -1, so that the paper is grooved directly after leaving me drying roll and before it has been cut into strips. The paper after being grooved and cut into strips may be sized and finished in the ordinary manner. I

From the foregoing description taken in connection with the drawings; it will be evident that we have produced a machine which accomplishesall the objects It herein set forth, and which is especially useful for forming flexible hinge portions in the paper used for leaves in ledgers and other such heavy books.

While we have stated that our invention is particularly adapted for attachment to a Eourdrinier machine,

and have shown and described the device as in connec- -"tion with such a machine, we would have it understood that our invention may be applied as well to any other type of paper-making machine.
